A cross-sectional study was carried out at Tianjin University campus, China, from February 21 to June10, 2006, to survey the association between dampness in dorms and allergy and airways infection among college students. The health and dampness condition were self-reported by 3436 students living in 1511 dorm rooms located in 13 buildings on the campus. The buildings were selected according to their positions, construction periods and occupant densities. The allergy and airways infection symptoms involved wheezing, dry cough during night, rhinitis, eczema, cold/flu, ear inflammation, pneumonia and tuberculosis. The indoor moisture signs were mould/damp spots on walls, ceilings and floors; suspected or ever happened water damage; condensation on windowpane in winter and odours perceived by subjects themselves. This study showed there was significantly positive association between condensation and dry cough. Eczema was often reported in rooms with suspected moisture problem. Dampness was a significantly risk factor for common cold.
This paper indicated that dampness problem at dorms of Chinese students was a risk factor in irritating allergic symptoms, and hence there is a need for dorm environment improvement. The ventilation and microbiology problems in dorm environment corresponding to dampness should be further studied, especially when it is associated to occupants' health.
2006年2月21日至6月10日在中国天津大学校园进行了一项横断面研究，以调查宿舍潮湿与大学生过敏及呼吸道感染之间的关联。居住在校园内13栋楼1511间宿舍的3436名学生自行报告了健康状况和潮湿情况。这些建筑根据其位置、建造时期和居住密度进行选择。过敏和呼吸道感染症状包括喘息、夜间干咳、鼻炎、湿疹、感冒/流感、耳部炎症、肺炎和肺结核。室内潮湿迹象包括墙壁、天花板和地板上的霉菌/湿斑；疑似或曾发生的水损；冬季窗玻璃上的冷凝水以及受试者自身感觉到的异味。该研究表明冷凝水与干咳之间存在显著正相关。在疑似存在潮湿问题的房间中经常报告有湿疹。潮湿是普通感冒的一个显著危险因素。
本文表明中国学生宿舍的潮湿问题是引发过敏症状的一个危险因素，因此需要改善宿舍环境。应进一步研究与潮湿相关的宿舍环境中的通风和微生物问题，尤其是当它与居住者健康相关时。
